The Kylie Jenner/Blac Chyna/Rob Kardashian drama continues. If you didn’t know, Rob’s fiancee Blac Chyna has a line of matte lipsticks, just like Kylie. The jury is out on who launched their collections first, as fans are quick to take the side of their fave celeb. As far as we know, Rob has never publicly supported his sister’s line, but he IS supporting Chyna’s, since he posted a video of her new colors last night.

Fans are accusing Rob of taking his fiancee’s side over his sister’s. Comments include "Direct roast on Kylie" and "oooooooh promoting his gf not his sister." Others say Chyna did it first, and why can’t he support his bae? "Chyna has had lash bar company way before Kylie…There is plenty of money to go around people," wrote one fan.

It’s extra dramatic because Chyna has been ~trolling~ Kylie on Instagram, posting memes that look like they are directed right at her. And ICYMI, Chyna used to date (and there was talk of engagement) Kylie’s BF Tyga, and they have a son together.
